Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33577812, here are decompositions:

31 + 33577781 = 33577812
239 + 33577573 = 33577812
241 + 33577571 = 33577812
283 + 33577529 = 33577812
311 + 33577501 = 33577812
353 + 33577459 = 33577812
383 + 33577429 = 33577812
431 + 33577381 = 33577812

Showing the first eight; more decompositions exist.
